Firefox Community Forum

Currently on Linux, but the problem is probably not OS-specific (although any work-around may be).

What I look for:

I want one setup for work, one for union, and one for personal use. If my work setup would be compromised, union bookmarks, search history etc is not compromised at the same time. Also, my work setup is not cluttered with private bookmarks and addons. Obviously, it'd be nice if those setups could be handled as separate start menue icons, so that I don't need to switch using a couple of clics, but just start the right setup directly. Needless to say nowadays, that these setups need to be syncable between devices. Ideally I as a person would have one Mozilla account that can store multiple profiles and protect each one with a seperate password, OR I as a person would have multiple Mozilla accounts that are made for easy switching.

What I've tried:

Multiple accounts, obviously; they sync between devices, which profiles really do not. The problem I run into is that I still need a separate profile for each account if I don't want to log in and out of them (which I don't want indeed, Alt-Tabbing during my leisure time is the only way for me to get things done for union and often for the office-part of work).

Finding the profile feature was hard enough but I adopted and have the about:profiles page bookmarked in all profiles. But whenever I start using a new computer, I need to set up new profiles. I tried saving them in a custom location on my nextcloud so that they can sync, but there is no straight forward way to import profiles. You need to create new ones and then move the contents of the old ones, instead of just pointing ff to an existing profile; that kind of kills the point of picking a custon location in the first place. All I ever do with a new profile is logging in to one of my already highly profiled accounts.

Along the way I realized that there is a now more GUI-way to create profiles, so I tried that. But when I tried choosing a custom location for them, I failed. Took me a while of restarting and googling to find out that Mozilla has managed to have two completely seperate features with the exact same name! That is, when you create a profile the modern way, it does not appear in about:profiles and vice versa.

Since I ditched the idea of custom location anyway, I setteled with the new way. But when I thought I'd make seperate startmenue links for them, because surely you can handle that with some kind of flag in the command, I could find only one option for profiles, and, as you can guess, it works with the old profiles.

It seems that one can start with a profile at a certain path, so maybe the old way with custom path could be something for me anyway, but when I used such a profile, I got a warning message that says that history and bookmark functions might not work properly and that some security program may cause this.

So, how is one actually supposed to use different accounts OR how is one supposed to sync different profiles between devices?

My impression is that everytime Firefox updates I loose my passwords and bookmarks. This happens on my windows and Linux computers. I believe that I'm not signed in to Firefox but not sure. Would not being logged in cause this problem?

I switched from Windows to Linux. I have signed in and tried retrieving bookmarks, browsing history and passwords, AFTER already having formatted my computer and deleted Windows. I signed in to the same account, had syncing on, but i can't seem to get any of the stuff back. I didn't have any additional backup files with those. Is there anyway i could somehow restore it all? The bookmarks are most important to me out of those. I'd be extremely grateful for any help

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

I am trying to find a way to restore the previous tabs that I had open. All the standard restore procedures out of the History button or elsewhere are not working due to the account change. Here's the background and scenario: Original account created 1 month ago on old Linux PC New PC purchased and Ubuntu Linux 24.04 installed Firefox installed and configured, bookmarks imported from .html file. No sync account was ever signed in to. Open a crapload of tabs that I wanted/needed to interact with (yes, I need a better task management system) Finally decide to log into sync account, successful sign-in Close browser for PC restart. Upon restart, all configurations from 1 month ago on old Linux PC are present, and no previously-opened tabs come back. Restore session/restore tabs/restore browser all are greyed out, no data to access in history anywhere. Signed out of account, closed browser window and restarted. Still displaying config from old sync account even when not logged in (different theme, toolbar settings)

I am unable to locate any files in the pathway Home/snap/firefox/common/.mozilla/firefox that clearly indicate multiple profiles; there is only one distinct profile folder present. I haven't cleared cache or anything, trying to not touch it more. Is it possible to restore or even see the URLs of those tabs from my session prior to logging in to my sync profile?
